Please show steps:

a. Which equation represents the supply curve, and which represents the demand curve? How do you know?

b. What is the equilibrium price and quantity in this market?

c. Graph the supply and demand curves for these equations.

d. Suppose the price is $8. What is the new Qs and Qd? What type of disequilibrium situation exists, and what is its magnitude? Briefly describe what will happen to bring the market back to equilibrium.
